I don't own cats but my step-great-grandmother kept Siamese indoors and one big fluffy cat who's breed I don't know of. My nan and her partner still have two, a red point and a torti Siamese. I believe its just what best fits an owners lifestyle to be honest. My nan and her partner are retired OAP's, live a relatively laid-back life and so do the cats. I live in a quiet little village in an estate about three roads from any main roads. I've got a neighbour who has had the same cat for as long as I moved to this house 15 yrs ago, he's aloud outside. She got a little girl about 5 years ago I'd say, she's been missing for about 2 of those years. A friend of mine has lost about 8 cats on the roads in our village, another friend of mine had a kitten knocked down right outside her house by a car, and that road has at least one car go down it per 15 minutes. Sometimes it is drivers being careless because cars have breaks, but on the other hand, yes, cats are stupid when it comes to road sense because they have none at all. If it were my cat, I'd rather have them inside the majority of the time, but for them to have access outside too if they wanna stretch their legs and go back to its roots by chasing a bird or whatever lol
